One user inserts a coin, then the next user tells what comes out of the vending machine that was used or has to do with Glee that the user before gets. Then that user inserts a coin and so on.

Example:

Ovybo: $Inserts coin$

Annoath:You get Emma's wedding gown
$Inserts coin$

gleegleek:You get Artie's wheelchair!
$Inserts coin$

And there you go! I hope Annoath and gleegleek didnt mind I used their usernames!
